12VDC To 120VAC Inverter - ElectroSuite.com

ElectroSuite.com – 12VDC To 120VAC Inverter. Q1 and Q2, as well as T1, determine how much wattage the inverter can supply. With Q1,Q2=2N3055 and T1= 15 A, the inverter can supply about 300 watts. Larger transformers and more powerful transistors can be substituted for T1, Q1 and Q2 for more power.

60 Hz Frequency Generator

60Hz Frequency Generator

The 60 Hz Frequency Generator circuit is very urgently needed to make the inverter or hardware related to the AC current voltage. This 60 Hz Frequency Generator is very simple and has a high accuration, the squarewave as the output which is precision.

The heart of this 60 Hz Frequency Generator is IC CD4060 as the IC Counter / Divider and also could be adjusted for the oscillator function. This IC and the crystal as the tank circuit, with the range of supply power from +5Vdc until +9Vdc. The tank circuit is formed by R1, VC1 and Xtal. VC1 as the tuning to make the value of the pulse frequency to get the best 60 Hz Frequency Generator.

Mini UPS using IC CD4047

Mini UPS using IC CD4047

This is Mini UPS using IC CD4047 Electro Suite, UPS (Uninterruptible Power Supply), is used to cope if the electricity goes out. Although not reliable as the original UPS, the circuit is a bit meaningless.

Simple and easy. The cost is relatively cheaper than buying the original UPS. The necessary components are also sold at many electronics stores.

This circuit has a power output of about 1.5 W. Before the main series there are a series of mini adapter that has a voltage between 9V/12V with a current of 500mA. The resulting voltage is used to operate the circuit and battery charge. The UPS is designed to keep electronic devices running despite power outages.

When the inverter is run with the AC input, and then converted into DC voltage. On the output rectifier is used to fill the battery. When a power failure or outage of electric current, DC voltage and then flows into an inverter that produces AC voltage at the output of the inverter.

The circuit is connected around the CD4047 IC that operates as a multivibrator at a frequency of 50 Hz. This multivibrator Q output drive MOSFETs IRF540. Inverter output is filtered and reduced use of MOV (Metal Oxide Vasitor). Transformer used is 9-0-9, 1.5A. Two LEDs (D6 and D7) are used as an indicator of whether the mains voltage or battery which is working.

Bel pintu Nirkabel menggunakan HEX Inverter 4069

Rangkaian Bel pintu Nirkabel menggunakan HEX Inverter 4069 ini sangatlah menarik. Bell pintu Nirkabel menggunakan HEX Inverter 4069 ini berjalan pada jalur frekwensi 303 MHz dan bisa bekerja dalam jarak kisaran 30 meter (100 Ft), tanpa menggunakan Antena!

Rangkaian ini sebenarnya bisa memancarkan sinyal dari jalur PCB yang tercetak pada papan rangkaian elektronik, berupa single-koil berbalik dan kapasitor kecil.

Rangkaian ini menghasilkan sinyal bersih 303MHz dan frekuensi ini terlalu tinggi untuk dideteksi atau diproses oleh chip 4069, sebagaimana chip 4069 hanya akan beroperasi sekitar 1MHz.
